ABA Extinction Concepts: Essential Glossary for RBTs

ABA therapy demands quick thinking for RBTs handling daily challenges. Understanding how to reduce unwanted behaviors safely is a key part of the job. A basic strategy is extinction, where you consistently withhold reinforcement for a problem behavior to decrease it. This ABA extinction concepts glossary defines key terms like "extinction burst" and "spontaneous recovery." It offers clear examples and insights for RBTs.
Mastering these concepts is vital for creating ethical and effective interventions. It's also essential for certification prep. This post will help you learn core extinction principles and how to document them for your BCBA team.
Here are the main takeaways from this glossary:
- Extinction involves withholding reinforcement to reduce a behavior.
- An extinction burst is a temporary increase in the behavior when extinction starts.
- Spontaneous recovery is the brief return of a behavior after it has been extinguished.
- A behavior's reinforcement history is a major factor in how resistant it is to extinction.
- Clear documentation is required to track progress and ensure ethical practices.
Understanding Key ABA Extinction Concepts
Extinction is a cornerstone of behavior reduction in Applied Behavior Analysis (ABA). It targets behaviors that are maintained by reinforcement. Extinction happens when a previously reinforced behavior no longer gets the consequence that kept it going. This causes the behavior to decrease over time. Following the BACB's ethics code, this process relies on consistently withholding reinforcement, like attention or escape from tasks.
For RBTs, it's important to know that extinction is not punishment. It focuses on removing a stimulus rather than adding one. Extinction is often paired with teaching replacement behaviors to encourage positive change. A real-world example is ignoring tantrums that previously earned a child a toy, which leads to the tantrums eventually stopping.
Defining the Extinction Burst
You'll often see an extinction burst as a common, early challenge in extinction procedures. This term describes a temporary spike in the frequency, intensity, or length of the target behavior right after reinforcement stops. The person is basically "trying harder" to get the reinforcer, as their learning history drives them to persist.
For example, a child who screams for candy might scream louder or longer when the candy is first withheld. This is the extinction burst. Basic and applied research on extinction bursts suggests that these bursts usually last for a few sessions if extinction is applied consistently. RBTs must be ready for this to avoid accidentally reinforcing the escalated behavior.
Exploring Spontaneous Recovery in ABA
Spontaneous recovery shows that extinction isn't always a straight line. It refers to the sudden return of an extinguished behavior after it hasn't occurred for a while. This can happen even if the extinction procedures are still in place. The behavior comes back because of its learned association with certain cues or after time away from therapy.
For instance, a client who had stopped head-banging might suddenly do it again during a stressful moment. This is spontaneous recovery. As explained in research on behavioral relapse, it often happens after breaks, like weekends, but gets weaker with repeated extinction. Recognizing this helps RBTs stay encouraged.
Extinction Burst vs. Spontaneous Recovery: Key Distinctions
Confusing an extinction burst with spontaneous recovery can mess up an intervention plan. The extinction burst definition is about an immediate escalation when reinforcement is first stopped. In contrast, spontaneous recovery happens later, after the behavior has already faded.
The burst hits right away, unlike recovery which pops up later. It's triggered by stopping rewards, not time gaps. And it lasts longer than those quick recovery blips. A tantrum spike on day one of a plan signals a burst. A flare-up weeks later after a vacation points to recovery.
Factors Influencing Resistance to Extinction
Not all behaviors go away at the same rate. Resistance to extinction is a measure of how stubbornly a behavior continues without reinforcement. High resistance means it will take longer to extinguish the behavior.
Several factors influence this:
- Reinforcement history: Behaviors that were reinforced on a variable schedule are harder to extinguish. Research on resistance to extinction shows that intermittent rewards build more persistence than continuous ones.
- Magnitude of reinforcement: Stronger or more frequent past rewards create greater resistance.
- Motivation and context: High-deprivation states or specific environmental cues can make a person try for longer.
Documentation Best Practices for Extinction Concepts
Accurate documentation ensures accountability and helps BCBAs make data-based adjustments. For RBTs, tracking extinction means detailing the procedures, the client's responses, and any side effects like bursts or recovery.
Your notes should include:
- Baseline data on the behavior's frequency, duration, and intensity.
- The specific extinction steps being used.
- Observations of any extinction bursts or spontaneous recovery.
- Progress metrics, like a decrease in the behavior over time.
- Data on any replacement behaviors being taught.
As outlined in the BACB ethics codes, thorough notes support team collaboration and compliance.
Frequently Asked Questions
What is the extinction burst definition in ABA?
An extinction burst is a temporary increase in the rate, duration, or intensity of a behavior right after reinforcement is stopped. It happens because the individual is trying to get the reinforcer back. It often lasts for a few sessions if the extinction plan is followed consistently.
What is spontaneous recovery in ABA?
Spontaneous recovery is the reappearance of a behavior that had been extinguished. It usually happens after a break from therapy or in a context similar to where the behavior used to be reinforced. It doesn't mean the plan failed, but that the learned association is resurfacing.
How does extinction burst differ from spontaneous recovery?
An extinction burst is an immediate escalation at the start of an extinction procedure. Spontaneous recovery is the return of a behavior later on, after it has already decreased. Guidance on extinction procedures highlights timing as the key difference.
What factors affect resistance to extinction in ABA?
Resistance to extinction is affected by the past reinforcement schedule, the strength of the reinforcer, and environmental cues. Consistency in withholding reinforcement and teaching alternative behaviors helps reduce it.
How should RBTs document extinction procedures?
RBTs must record baseline data, the exact steps for withholding reinforcement, and all occurrences of bursts or recovery. Notes must be objective and timely to evaluate the plan's effectiveness, as required by the BACB's professional and ethical code.
Are there examples of extinction in everyday ABA therapy?
Yes. A common example is withholding attention for attention-seeking behaviors like whining. Another is escape extinction, where a client is not allowed to avoid a task by engaging in problem behavior. Case studies on extinction show how it's often paired with teaching a replacement behavior for the best results.
As RBTs use this ABA extinction concepts glossary, remember that these principles are a toolkit for ethical practice. By thoughtfully withholding reinforcement and documenting everything, you help clients make lasting gains. Combining extinction with positive strategies always yields the best results.
